Gyms are buildings in which a person can do physical exercise. Gyms contain the relevant equipment to fulfil most needs when doing physical exercise, including cardio machines, weights and swimming pools. Gyms can also offer exercise classes such as aerobics for those who wish to exercise but don't want to use the equipment in the gym. They are staffed by trained instructors who understand how the equipment works and can therefore help users. Some examples of cardio equipment include treadmills, rowing machines, exercise bikes and cross trainers. There are several machines available to assist with using weights as well as free weights that one can use as a standalone.
